SAWATA Geological Research Project, Prince ofSongkhla University, Thailand On 23 June 1977, Prof. N .S. Haile, head (Dr. Morris' letter dated 14th July 1977 to of the Department of Geology, University of Prof. Haile). Prof. Haile also suggested dating Malaya at that time, sent a letter to the of suitable samples from the locality, since writer enclosing a photostat copy of a this would give an estimation of the rate of photograph showing the location of fossil build out of the coast, as the crabs plus crabs and fossilized cuttlefish bone. He cuttlefish would seem to indicate a shore guessed the deposit containing fossils is line; he suspected the age was about 5,000 Pleistocene or perhaps Pliocene and years. considered it would be interesting to see On 22 October 1978, the writer had a whether there are any foraminifera or other chance during his holiday trip to visit the fossils there. fossil locality with the kind guidance ofMiss The British Museum studied the Patcharin Phannanukul, chief of Japanese samples of these fossils sent by Prof. Haile course of this university and her brother-in and determined the cuttlefish is Sepia law. bandensis Adam (identified by Dr. M.K The attached sketch map (Fig. 2) shows Howarth) and the crabs areMacrophthalmus the locality(loc. 1 in Fig. 3). Unfortunately, (Venitus) latreillei (Desmarest) (identified the high level of water in the Muno Canal by Dr. S.F. Morris) (Figs. 1,4-6). Dr. Morris prevented him from doing any geological writes that it ranges from Pleistocene to study of the outcrop of locality itself, and Recent and usually lives in estuaries or only small amounts of imperfect fragments mangrove swamps. This species is known of crab fossils and white stone - cuttlefish from the Pleistocene ofSabah and Ceylon; it bone fossil? - were shown to him by local is common as a sub-fossil from the Chinese inhabitants and one fragment of crab fossil coast and northern Australia. Its was presented by one of them. The local geographical range as an extant species people related that one or two years before covers most of southeast Asia, from the Gulf about a thousand pieces offossil were found of Bengal to Japan and northern Australia in the canal, and a buyer from Bangkok exhausted all the collection.
